ClassFile.build() is loading result file

[Mark Roberts]

I am using ClassFileTransformer.transform() to instrument class files as
they are loaded.   Within my transform method I call



byte[] newBytes =  classFile.build(classModel.thisClass().asSymbol(),

                          classBuilder -> modifyClass(classBuilder,
classModel, loader));



where modifyClass does all the instrumentation.



The problem is some where inside of classFile.build() the class is actually
being loaded!  Thus, when I return newBytes from the transform method I get
an error ‘attempted duplicate abstract class definition’. I have verified
that the class has not be loaded prior to the return from modifyClass().



What is going on?



Thank you,

Mark
